摘要： The present patent application refers to a nutritional formulation presented as animal feed, concentrate and supplement, with extruded characteristic, based on crop haystacks or culture residues, with the object to complement or provide nutritional requirements for ruminants and/or equines, disclosing a product with considerable reduction of the final cost, due to the abundance of the raw material as used being originated from annual crop haystacks, improving the utilization of the food contained in the final product, with gains of digestibility, consequently improving the effectiveness of the rational use of nutritional resources with those species.

摘要： Animal feed formed with a base of palm fronds and combined with palm fruit, such as dates, is a sustainable and affordable feed product that can be developed in hot climates. Palm fronds with a desired moisture content are shredded, chopped, and/or ground, and mixed with palm fruit. Additives such as urea can increase the nutritional content. Feeds with palm fronds, palm fruit, and/or additives can serve as a base feed for other components. Palm fronds can also serve as a base feed for other components. Animal feeds with a variety of bases can have palm fruit added. Animal feeds with a variety of bases, including palm fronds, can include a variety of other components added.

摘要： A novel method of reducing the melting point of a peptide-based biopolymer using a nitrogen-containing compound as a plasticizer is provided. The peptide-based biopolymer can be keratin or silk. The nitrogen-containing compound can be one or more amino acids or other nitrogen-containing compounds (except urea), all of which have a melting temperature above approximately 133° C., the decomposition temperature of urea. Pellets made using this novel process can be used as animal feed and soil amendments (fertilizer) to increase the adsorption of amino acids in the animal or in the soil, respectively.

摘要： A process is described comprising neutralization with ammonium hydroxide of the reaction mixture generated by the hydrolysis of 2-hydroxy-4-methylthio-butyronitrile by sulphuric acid, so as to obtain an aqueous phase and an organic phase which, once separated, are subjected to evaporation to remove the ammonium sulphate formed. For the aqueous phase, this sulphate is removed as a byproduct; and for the organic phase, it is recirculated to the neutralization vessel. The 2-hydroxy-4-methylthio-butyric acid obtained from the organic phase is subsequently diluted with water and possibly stabilized with sulphuric acid. The product obtained is useful as a food supplement in animal diets.

摘要： Process for the production of technical grade biuret, readily in a form suitable for use as animal feed, by the controlled pyrolysis of urea in two stages, the first stage involving the partial pyrolysis of urea at a temperature above the melting point of urea to produce a first stage intermediate reaction product containing from about 20% to about 60% urea, and not more than about 25% cyanuric acid by weight, such reaction product being then cooled and comminuted, the comminuted product then being subjected, in solid form and in the absence of a liquid carrier, to a temperature at or slightly below the softening point of the solid particulate (suitable at a temperature of from about 100.degree. C. to about 140.degree. C.) with forced air circulation through the comminuted product for a sufficient time to lower its urea content by partial sublimation of the urea and partial further reaction thereof to biuret with only minimal further conversion of urea to cyanuric acid. Crystallization and cooling of the molten intermediate product resulting from the first stage of pyrolyzation is advantageously accelerated by addition thereof of a powdered seed material, preferably including powdered feed grade biuret from a previous run, which additive serves to also increase the melting point of the product and thus increase the temperature at which it may be heated during the solid state pyrolyzation.

摘要： A homogeneous, free-flowing urea containing composition which has particular utility as an animal feed supplement or a fertilizer material and an improved process for preparing same are disclosed. In the process urea and particular forms of calcium sulphate are intimately mixed, optionally with calcium phosphate and one or more desired additives, and pelletized or granulated as by compression compaction. In one embodiment, micronutrients are blended into the urea-calcium sulphate mixture before compaction and the granules so produced may be subsequently utilized as a fertilizer supplement or in combination with primary nutrients as a complete fertilizer. In a second embodiment, the urea-calcium sulphate constitute an animal feed supplement to be blended with other, non-hygroscopic, nutrients such as calcium phosphate and the like in forming a silage or complete animal feed.
